FORD 2010 Fusion v.3 - Manual (Page 216)

• Provides additional engine braking through the automatic transmission
shift strategy which reacts to vehicle inputs (vehicle acceleration,
accelerator pedal, brake pedal and vehicle speed).
• Allows the transmission to select gears that will provide the desired
engine braking based on the vehicle inputs mentioned above. This will
increase engine RPM during engine braking.
Grade assist is designed to provide optimal gear selection in hilly terrain
or mountainous areas. It is recommended that you return to grade assist
on flat terrain to provide the best fuel economy and transmission
function.
To return to grade assist, press the transmission control switch again.
• The grade assist lamp in the instrument cluster will not be illuminated.
• The transmission will operate in gears one through six.
Grade assist is automatically returned each time the key is turned off.
L (Low)
This position:
• Provides increased engine braking during downhill/mountain driving.
• Provides extended shift scheduling, allowing both upshifts and
downshifts, at a higher overall RPM to provide optimum engine
braking.
• Is not intended for use under extended or normal driving conditions
and results in lower fuel economy.

(if equipped)
Your vehicle has been designed to improve fuel economy by reducing
fuel usage while coasting or decelerating. When you take your foot off
the accelerator pedal and the vehicle begins to slow down the torque
converter clutch locks up and aggressively shuts off fuel flow to the
engine while decelerating. This fuel economy benefit may be perceived
as a light to medium braking sensation when removing your foot from
the accelerator pedal.
